SPILERIUM  OF  NORTH  AND  SOUTH  AMERICA. 


The  genus  Sphserium  was  characterized  under  its  present  name  by  Scopoli, 
in  1777  ;  since  that  time,  however,  it  has  received  various  denominations, 
and  the  one  under  which  it  has  been  most  generally  known,  that  of  Cyclas, 
was  applied  to  it  in  1792  by  Bruguiere.  'Mr.  Gray  revived  the  term  of  Sphse- 
rium in  1847,  and  his  example  has  been  followed  by  the  conchologists  of  the 
continent  of  Europe.  I  was  the  first  in  this  country  to  discard  the  name  of 
Cyclas  for  that  of  Sphserium. 

The  species  composing  this  genus  are  small  bivalves  inhabiting  rivers, 
lakes,  streams,  and  still  waters  ;  they  are  plentifully  distributed  all  over  the 
globe,  but  as  far  as  present  experience  goes,  seem  to  be  more  abundant  on 
the  northern  portion  of  this  hemisphere  than  elsewhere. 

The  shell  is  transversely  oval,  nearly  equilateral,  thin,  fragile,  sometimes 
translucent,  with  beaks  more  or  less  raised  ;  its  entire  surface  is  transversely 
striated  and  covered  with  a  light  epidermis  varying  in  color ;  the  margins  are 
rounded,  obtuse  or  angular.  The  interior  of  the  valves  is  smooth  and  varies 
in  color  ;  the  muscular  impressions  are  not  very  distinct ;  the  posterior  one 
is  slightly  the  largest ;  the  palleal  impression  is  parallel  with  the  basal  mar- 
gin ;  it  is  narrow  and  always  simple.  The  hinge  margin  is  very  variable  ;  it 
is  usually  composed  of  two  small  teeth  in  each  valve ;  at  times,  however,  they 
are  single  in  one  and  double  in  the  other,  or  else  single  in  both  valves  ;  these 
teeth  are  occasionally  rudimentary,  or  even  nearly  obsolete.  The  lateral 
teeth  placed  on  each  side  of  the  cardinal  teeth  are  double  in  the  right  valve 
and  single  in  the  left  one  ;  the  anterior  lateral  tooth  is  usually  the  shorter. 
The  ligament  is  external ;  it  is  short,  not  very  conspicuous,  and  is  always 
found  on  the  longer  portion  of  the  shell. 

The  animal  of  Sphserium.  has  a,  broad  foot,  capable  of  considerable  exten- 
sion ;  it  uses  it  either  to  bore  holes  in  the  mud,  in  which  it  sinks  the  poste- 
rior portion  of  the  shell,  or  as  means  of  locomotion.  The  syphonal  tube  is 
double  and  very  retractile  ;  it  is  often  white  like  the  foot  but  at  times  it  is 
colored. 

The  habits  of  these  molluscs  are  very  similar  to  those  of  Pisidium,  with 
which  they  are  often  found  living.  The  species  of  Sphserium  are  less  abun- 
dant in  individuals  than  those  of  Pisidium  ;  they  are  also  less  generally  dis- 
tributed, and  are  more  confined  to  certain  localities  than  the  latter.

Generic  characters.  Animal  oval,  lobes  of  the  mantle  simple,  united  poste- 
riorly and  terminating  in  two  short  syphons,  joined  at  their  base,  without 
tentacles  ^ mouth  oval  shaped,  small ;  tentacles  of  the  mouth  short  and  nar- 
row ;  gills  rather  broad,  nearly  equal,  united  behind  the  foot ;  foot  narrow, 

el°snheneoval,  nearly  equilateral;  beaks  somewhat  inflated  and  prominent ; 
hin^e  margin  narrow,  with  two  primary  teeth  in  each  valve  ;  lateral  teeth 
elongated;  palleal  impression  simple;  ligament  external,  narrow,  situated  on 
the  longer  portion  of  the  shell.

(Cabinet  Acad.  of  Nat.  Sci.  of  Phila.,  Garden  of  Plants  in  Paris,  Mus.  De- 
lessert,  Jay,  Prime  and  others.) 

This,  our  most  common  and  widely  distributed  species,  living  as  it  does  in 
so  many  different  sections  of  the  country,  presents  at  times  great  variations 
in  size,  color  and  general  appearance.  It  can,  however,  be  easily  recognized 
by  its  very  elongated  and  equilateral  form,  and  by  the  beaks  which  are  uni- 
formly full  and  convex  ;  they  are  often  eroded.  The  young  is  often  of  an 
uniform  light  lemon  color,  which,  as  the  shell  matures,  becomes  gradually 
darker  from  the  beaks  downwards  until  the  new  shade  covers  the  whole  sur- 
face of  the  shell ;  in  certain  intermediate  stages  of  growth,  the  shell  is  marked 
with  a  zone  of  yellow  on  the  inferior  margin ;  the  color  of  the  adult  varies 
from  a  greenish  brown  to  a  dark  chestnut.  The  young  shell  has  at  times, 
owing  to  the  variations  which  exist  between  it  and  the  adult,  been  taken  for  a 
different  species  ;  by  some  it  has  been  taken  for  the  Sph.  rhomboideum. 

*  I  ana  preparing  for  publication,  as  a  complement  to  this  Monagraph,  an  Atlas  with 
colored  figures  of  the  different  species  described. 


The  hinge  margin  is  generally  straight.  I  have  specimens,  however,  from 
Alabama,  Pennsylvania  and  Rhode  Island,  in  which  it  is  slightly  curved.  One 
of  the  distinctive  characters  of  this  species  is  that  the  lateral  teeth  are  never 
placed  at  an  angle  with  the  cardinal  teeth ;  they  are  generally  on  a  straight 
line  with  them. 

The  finest  specimens  I  have  seen  of  the  Sph.  s  u  1  c  a  t  u  m  were  sent  to  me 
by  Mr.  Ingalls,  who  had  collected  them  in  Washington  Co.,  N.  Y.  ;  they  were 
remarkably  convex,  and  measured  as  much  in  length  as  13-16ths  of  an  inch  ;  the 
beaks  were  very  full,  and  much  raised  above  the  margin  of  the  shell. 

This  species  was  first  described  in  1818,  by  Lamarck,  under  the  names  of  Cy- 
clas  s  u  1  c  a  t  a  and  Cyclas  Saratoga  a.  Say,  in  1819,  ignorant  that  this  shell 
was  known  to  conchologists,  described  it  as  the  Cyclas  s  im  i  1  i  s,  under  which 
name,  until  very  recently,  it  has  been  most  generally  known.  Say  also  fig- 
ured this  species,  but  his  figure,  I  regret  to  say,  is  not  correct,  and  would  be 
more  apt  to  give  one  the  idea  of  a  Pisidium  than  of  a  Sphaerium.  The  descrip- 
tion by  Say  of  the  Cyclas  s  i  m  i  1  i  s  applies  perfectly  to  the  shell  under  con- 
sideration, of  which  Dr.  Gould  has  given  a  very  good  figure  in  his  Report  on  the 
Invertebrata  of  Massachusetts. 

As  related  elsewhere,*  I  had  an  opportunity,  some  years  since,  while  in 
Paris,  to  see  Lamarck's  original  specimens  of  the  Cyclas  s  u  Ic  at  a  and  S  a  r  a- 
togea,  at  the  Garden  of  Plants,  and  at  the  Delessert  Museum  ;  and  to  con- 
vince myself  by  examination  that  they  both  belonged  to  one  species,  and  were 
identical  with  Say's  Cyclas  s  i  m  i  1  i  s.

Animal,  not  observed. 

Shell  transversely  oval,  slightly  elongated,  nearly  equilateral,  heavy,  con- 
vex ;  beaks  full,  raised  above  the  outline  of  the  shell ;  anterior  margin  broad 
and  rounded ;  posterior  narrower  and  somewhat  angular ;  inferior  slightly 
curved ;  hinge  margin  somewhat  broad,  curved ;  cardinal  teeth  diminutive, 
double,  so  placed  together  as  to  represent  the  form  of  the  letter  V  reversed, 
and  rather  wide-spread  ;  lateral  teeth  situated  each  one  at  an  angle  with  the 
cardinal  teeth,  strong  and  large ;  sulcations  deep,  not  very  regular ;  epidermis 
varying  from  a  greenish  yellow  to  a  bright  gold  color,  slightly  lustrous  ;  inte- 
rior of  the  valves  bluish  white. 

Long.  9-16 ;  lat.  7-16 ;  diam.  6-16  inches. 

Hab.     North  America,  from  Lake  Superior  ? 

(Cabinet.    Agassiz  and  Prime.) 

This  is  one  of  our  most  attractive  species,  but  also  one  of  the  rarest.  It  is 
supposed  to  have  been  brought  from  Lake  Superior  by  the  expedition  which 
visited  that  region  under  Professor  Agassiz.  In  general  outline  it  offers  some 
similarities  with  the  Sph.  s  u  1  c  a  t  u  m  ;  it  is,  however,  a  much  more  ponderous 
shell ;  it  is  less  elongated,  more  convex,  its  sulcations  are  not  so  regular,  its 
color  is  different,  and  lastly,  its  hinge  margin  is  much  more  curved. 

Compared  to  the  Sph.  s  o  1  i  d  u  1  u  m,  it  is  more  convex,  more  elongated,  its 
posterior  margin  is  broader,  the  hinge  margin  is  not  so  much  curved,  the  beaks 
are  fuller,  and  the  sulcations  are  not  quite  so  heavy  ;  the  color  is  also  dif- 
ferent.

This  species  which  is  not  uncommon  was  probably  confounded  by  our  early 
oouchologists  with  the  Sph.  s  u  1  c  a  t  u  m,  it  differs  from  that  shell,  however,  in 
being  less  elongated,  more  inequilateral,  less  convex,  the  hinge  margin  is 
more  curved,  and  the  shell  is  more  solid.

As  may  be  seen  by  the  above  synonymy,  I  have  been  induced  to  unite  under 
this  species  several  which  I  described  as  distinct  in  1851.  The  differences  ex- 
isting between  these  shells  are  at  times  quite  marked,  but  in  general  charac- 
ters they  agree,  and  I  am  inclined  to  believe  that  these  differences  owe  their 
origin  solely  to  local  causes. 

I  had  occasion  some  time  since  to  convince  myself  of  the  identity  of  the 
Sph.  striatinum  with  the  Cyclas  edentula  of  Say.* 

This  species,  which  is  not  unplentiful  in  the  localities  where  it  is  found, 
varies  much  in  size,  color  and  external  appearance  generally.  The  shell  from 
Connecticut  is  so  slight,  that  it  is  nearly  translucent,  and  the  striae  are  so 
light  as  to  impart  to  it  a  lustrous  appearance  ;  on  the  other  hand,  I  have  spe- 
cimens from  the  Hoosack,  which  are  quite  heavy  and  coarsely  striated  ;  in 
the  main,  however,  they  all  seem  to  tally.  The  variety  from  Alabama,  descri- 
bed as  the  Cyclas  ten  u  is  tr  iat  a,  is  less  distended,  is  fuller,  and  the  sul- 
cations are  hardly  perceptible.

Compared  to  the  Sph.  s  o  1  i  d  u  1  u  m ,  this  species  is  smaller,  more  inequi-

I  have  been  induced  to  unite  to  this  species  the  Cyclas  f  u  s  c  a  t  a  ,  Rafin- 
esque,  which  I  consider  as  nothing  more  than  a  large  variety.  The  Cyclas 
bulbosa,  Anthony,  is  a  little  more  globose  than  Mr.  Conrad's  typical  speci- 
mens, but  presents  no  important  characters  of  difference.  The  shells  of  this 
species  found  in  New  Jersey  and  in  Illinois,  are  larger  than  those  from  Ala- 
bama. 

This  species  differs  from  most  of  our  North  American  ones  by  its  full  and 
very  prominent  beaks.

This,  the  most  attractive  species  of  Sphcerium,  is  not  easily  confounded 
with  any  other.  Up  to  within  a  few  years  it  was  usually  known  among  col- 
1  ectors  under  the  name  of  Cyclas  e  1  e  g  a  n  s,  Adams.  I  have  stated  elsewhere* 
my  reasons  for  considering  the  Cyclas  elegansas  identical  with  Say's  shell. 
Though  no  longer  rare  since  1851,  when  Mr.  Whittemore  found  it  in  consider- 
able abundance  at  one  place  near  Cambridge,  Mass.,  this  species  does  not 
seem  to  be  very  widely  distributed ;  it  is  confined  to  certain  special  locali- 
ties.

The  young  shell  is  more  elongated  and  more  heavily  sulcated  than  the 
adult ;  the  beaks  are  less  large  and  less  tumid.  This  is  a  well  marked  species, 
compared  to  the  Sph.  patella,  Gould,  from  the  same  section  of  the  country 
it  is  found  to  be  larger,  more  ventricose,  the  beaks  are  more  inflated,  and  the 
color  of  the  epidermis  is  different. 

The  only  two  specimens  I  have  seen  of  the  Sph.  dentatum  were 
those  from  which  Mr.  Haldeman  described  the  species,  an  adult  and  a  young 
one,  which  he  was  kind  enough  to  lend  me  for  study  ;  they  are  now  deposited

This  is  a  very  distinct  species ;  I  know  of  no  other  to  which  it  bears  any 
resemblance  ;  it  is  remarkable  for  its  compressed  appearance,  and  for  the  de- 
pression of  its  beaks.  Though  pretty  widely  distributed,  it  does  not  seem  to 
be  found  any  where  in  much  abundance. 

The  epidermis  of  the  shell  is  at  times  so  entirely  stained  with  a  darkish 
substance,  that  it  is  with  difficulty  that  its  color  can  be  detected.

The  triangular  and  very  tumid  form  of  this  species  is  quite  singular ;  it 
differs  from  the  Sph.  Vermontanum  in  being  more  tumid,  fuller,  in  having 
larger  beaks  and  in  being  much  less  broad  at  the  base.  The  young  shell  is

This  is  a  very  slight  and  delicate  species,  quite  distinct  from  any  others  but 
the  Sph.  patella,  to  which  it  bears  some  general  resemblance  from  its  shape  ; 
it  is,  however,  more  compressed,  less  high,  and  the  exterior  of  the  valves  is 
very  different,  as  they  are  nearly  smooth  in  Dr.  Gould's  shell.  Found  not

The  specimens  from  which  I  have  prepared  this  description  were  presented 
to  the  Academy  of  Natural  Sciences  of  Philadelphia  by  Mrs.  Say,  as  the  Cyclas 
triangularis,  Say  ;  they  may  or  may  not  be  true  representatives  of  Say's 
species.  In  many  points  they  answer  his  description  of  the  C.  triangularis, 
but  at  the  same  time  I  am  not  able  to  reconcile  their  shape,  which  is  not  more 
triangular  than  that  of  any  other  species,  with  the  name  he  has  applied  to 
the  species.  Moreover,  they  bear  a  very  strong  resemblance  to  one  of  out- 
Northern  Sphserium,  the  Sph.  solidulum;  they  differ  from  it,  however,  in 
being  less  heavily  and  more  regularly  striated,  and  in  having  more  prominent 
beaks.

Hab.  N.  America,  at  New  Orleans,  La.,  and  in  Florida  and  Alabama. 
(Cabinets  Acad.  Nat.  Sci.  Philada.,  and  Prime.) 

Remarkable  for  its  transversely  spherical  shape,  which  renders  it  distinct 
from  all  other  species  of  this  genus.  It  is  much  more  solid  than  the  generality 
of  calyculate  species,  the  valves  being  as  strong  as  those  of  any  of  the  larger 
species  of  the  preceding  group. 

The  Cyclas  pallida,  the  young  of  this  species,  is  more  delicate  than  the

color  is  bright  yellow.

Academy  of  Natural  Sciences,  though  very  perfect  in  appearance,  comprised 
but  a  single  valve. 

This  species  seems  to  be  very  rare.  I  have  never  met  with  any  other 
specimens  but  the  one  in  the  cabinet  of  the  Academy  and  those  I  have  in 
mine, — two  specimens  of  the  Cyclas  pallida,  derived  from  De  Charpentier 
himself,  and  a  single  valve  from  Florida.

Animal  usually  white,  in  some  varieties  pink,  syphonal  tubes  pink.  Shell 
rounded-oval,  thin,  fragile,  pellucid,  somewhat  inflated,  nearly  equilateral ; 
anterior  margin  very  slightly  distended,  rounded ;  posterior  slightly  abrupt  ; 
basal  rounded ;  beaks  central,  calyculate,  approximate  at  apex  ;  striae  so  deli- 
cate as  hardly  to  be  visible  ;  epidermis  glossy,  of  a  light  greenish  horn  color, 
with  at  times  a  zone  of  a  different  shade  on  the  basal  margin ;  valves  delicate, 
moderately  convex,  interior  light  blue  ;  hinge  margin  nearly  straight,  passing 
by  a  regular  curve  into  the  anterior  margin,  bat  curving  suddenly  behind,  so 
as  to  form  an  obtuse  angle,  causing  the  posterior  side  to  appear  broader,  thus 
givino-  the  shell  a  somewhat  rhombiform  appearance  ;  cardinal  teeth  strong, 
assuming  the  shape  of  the  letter  V  reversed;  lateral  teeth  very  much 

The  young  shell  is  more  compressed  than  the  adult ;  it  is  usually  light 
yellow.

This  species  varies  much  according  to  the  localities  where  it  is  found,  which 
accounts  in  part  for  the  number  of  names  it  has  received.  The  Cyclas 
erbicularia,  of  which  I  have  authentic  specimens  from  Mr.  Barrat,  is  a 
genuine  Sph.  partnmium,  without  even  any  local  modifications  of  shape. 
The  Cyclas  m  i  r  a  b  i  1  i  s  ,  from  Georgia,  is  a  small  form  of  this  species,  and 
the  Cyclas  c  oe  r  ul  e  a  differs  from  the  type  in  being  a  little  less  inflated.  The 
Gyclas  e  b  u  r  n  e  a  ,  from  Arkansas,  varies  from  the  Northern  Sph.  p  a  r  t  u- 
m  i  u  m  in  being  more  compressed  and  a  little  more  elevated.  I  do  not  think, 
however,  taking  the  difference  of  localities  into  consideration,  that  these  are 
characters  sufficient  to  warrant  retaining  the  Cyclas  eburnea  as  a  distinct 
species.  I  had  an  opportunity  while  in  Paris  to  assure  myself  that  the  variety 
No.  2  of  Cyclas  cornea  was  a  true  Sph.  partumium. 

This  species  is  not  only  very  widely  distributed,  but  where  it  is  found,  it 
occurs  in  large  numbers.  The  only  one  of  our  Northern  species  to  which  it 
bears  much  resemblance  is  the  Sph.  truncatum,  and  that  is  only  in  general 
outline;  the  Sph.  partumium  is  much  more  inflated  and  transversely 
more  broad.

This  attractive  and  rare  species  is  easily  distinguished  by  its  elevated  shape 
and  by  its  abrupt  lateral  margins,  which  give  it  a  somewhat  triangular 
appearance.  It  is  related  to  the  Sph.  Ryckholti  of.  Europe,  from  which 
it  differs,  however,  in  being  more  inflated,  its  beaks  are  less  prominent,  the 
shell  is  more  elevated,  and  its  anterior  margin  is  abrupt,  whereas  in  Sph. 
Ryckholti  it  is  distended  and  angular.

It  has  not  been  my  good  fortune  to  meet  with  this  species.  M.  D'Orbigny 
says  it  bears  some  resemblance  to  the  Cyclas  caliculata,  meaning  thereby, 
I  presume,  the  shell  now  known  to  European  conchologists  under  the  name  of 
Sph.  lacustre,  Ferussac.

This  species,  the  smallest  one  known  to  inhabit  the  United  States,  was  dis- 
covered some  years  since  by  Mr.  CKrard,  from  whom  I  obtained  my  specimens, 
the  only  ones  I  have  met  with.  It  may  possibly  be  the  young  of  some  species, 
but  if  so,  it  would  be  very  difficult  to  say  which  ;  setting  aside  its  diminutive 
size,  it  appears  to  have  all  the  characteristics  of  a  mature  shell.  In  outline  it 
seems  to  be  allied  to  the  Sph.  transversum;  it  is,  however,  more  inflated, 
less  elongated,  and  its  margins  are  more  rounded.  At  first  sight,  it  might 
readily  be  mistaken  for  a  Pisidium.

This  large  and  delicate  species  is  remarkable  for  its  very  transverse  shape 
and  for  the  narrowness  of  the  anterior  extremity  as  compared  to  the  posterior.

The  form  of  the  shell  recalls  that  of  many  of  the  small  species  from  the  West 
Indies  and  South  America.  It  is  found  in  considerable  abundance. 

The  Cyclas  detruncata  does  not  differ  sufficiently  from  the  type  to  con- 
stitute even  a  variety.  The  Cyclas  g  r  a  c  i  1  i  s  is  a  large  variety  of  Sph.  trans- 
v  e  r  s  u  m,  it  is  a  little  more  inflated  and  of  a  darker  color.  The  Cyclas  c  o  n- 
s  t  r  i  c  t  a  is  nothing  more  than  a  difformed  specimen  of  Say's  species,  having  a 
perpendicular  furrow  up  the  centre  of  each  valve,  caused  by  some  accident 
occurring  to  the  shell  during  its  growth.

This,  the  smallest  species  of  Sphaerium,  has  the  peculiar  appearance  cha- 
racteristic of  the  West  Indian  and  South  American  shells  of  this  genus.  It 
does  not  seem  to  be  uncommon.  Some  authors,  led  away  by  its  diminutive 
size,  have  committed  the  error,  as  may  be  seen  by  the  above  synonymy,  of 
placing  it  under  the  head  of  Pisidium.  I  have  never  seen  the  Cyclas  m  a  c  u- 
lata  of  Anton,  (non  Morelet,)  but  have  every  reason  to  believe,  from  the 
description  given  of  it,  that  it  does  not  differ  materially  from  this  species.  In 
outline  it  is  somewhat  similar  to  the  Sph.  Barbadense;  it  is,  however, 
much  smaller,  less  inflated,  and  the  beaks  are  much  more  raised.  Compared 
to  the  Sph.  meridionale,  Nobis,  and  Sph.  maculatum,  Morelet,  it  is 
smaller,  more  inflated,  and  the  margins  are  more  rounded.

The  specimen  from  which  this  description  was  prepared— the  original  shell 
from  which  Mr.  Haldeman  described  the  Pisid.  diaphann  m — is  in  the 
Cabinet  of  the  Academy  of  Natural  Sciences  of  Philadelphia.  It  was  dis-

the  Cyclas  modioliformisor  the  Pisid.  Moquinianum,  but  judging 
from  their  descriptions  and  from  the  figure  of  the  latter,  I  have  little  doubt 
but  that  they  belong  to  the  same  species.  I  have  had  occasion  to  examine 
the  Cyclas  striatella,  littoralis  and  Venezuelensis  personally. 

The  Sph.  modioliforme  seems  to  be  rare.  It  bears  some  resemblance 
to  the  Sph.  meridionale,  but  it  differs  from  it  in  being  more  inflated  and 
of  a  lighter  color.

and  South  American  Sphseria  by  its  sulcations,  which  are  regular  and  deep. 
In  shape  and  appearance  it  recalls  the  young  of  Sph.  sulcatum.  It  is 
allied  to  Sph.  Veatleyi  in  outline,  but  otherwise  it  is  different,  in  being 
heavier  and  of  a  larger  size.

Animal  pinkish,  syphons  of  the  same  color.  Shell  rhombic-orbicular,  veu- 
tricose,  subequilateral,  both  sides  of  very  nearly  the  same  length ;  anterior 
margin  a  little  curved  ;  posterior  margin  abrupt,  forming  an  obtuse  angle  with 
the  hinge  margin;  basal  margin  much  longer  than  the  superior  margin, 
rounded  ;  beaks  large,  calyculate,  slightly  inclined  towards  the  anterior,  very 
approximate  at  apex ;  valves  slight,  very  convex,  especially  in  the  region  of 
the  umbones  ;  strise  delicate,  regular,  hardly  perceptible  ;  epidermis  glossy  in 
some  cases,  very  variable  in  color,  but  generally  of  a  greenish-horn,  at  times 
of  a  brilliant  yellow  or  straw  color ;  hinge  margin  curved,  narrow ;  cardinal 
teeth  very  small,  united  at  base ;  lateral  teeth  slight,  elongated,  very  narrow. 
Long.  6-16  ;  lat.  5-16  ;  diam.  4-16  inches. 

Hab.    N.  America,  in  the  States  of  Massachusetts,  Vermont,  Pennsylvania 
and  New  York.     (Cabinets  Jay,  Lewis  and  Prime.) 


IT 

Found  plentifully  at  Cambridge,  Mass.  I  cannot  see  differences  sufficient  be- 
tween the  Sph.  s  e  c u  r i s  and  the  Cyclas  cardissa  to  separate  them  ;  the 
Cyclas  cardissa  is  more  globose,  transversely  shorter,  more  elevated,  but 
still  intermediate  forms  uniting  the  two  are  so  frequent  that  it  is  not  possible 
that  they  should  form  distinct  species. 

The  Cyclas  c  r  o  c  e  a ,  Lewis,  is  a  young  of  this  species. 

Compared  to  the  Sph.  sphsericum,  the  Sph.  securis  is  more  equilateral, 
the  beaks  are  less  tumid  and  less  inclined,  the  sides  are  less  rounded,  and  the 
hinge  margin  is  less  curved. 

31.  Sph.  rosaceum,  Prime. 

Cyclas  rosacea,  Prime,  Bost.  Proc.  iv.  155,  1851. 

Animal  not  observed.  Shell  small,  rounded-oval,  fragile,  translucent,  sub- 
equilateral,  somewhat  compressed,  margins-  generally  rounded ;  beaks  nearly 
central,  slightly  inclined  towards  the  anterior,  calyculate,  approximate  at 
apex  ;  valves  very  slight,  a  little  convex  in  the  region  of  the  umbones  ;  strise 
regular,  hardly  visible  ;  epidermis  shiny,  reddish-brown  ;  hinge  margin  nearly 
straight,  delicate,  narrow ;  cardinal  teeth  nearly  obsolete,  lateral  teeth  slight, 
elongated. 

Long.  4-16 ;  lat.  3-16  ;  diam.  5-32  inches. 

Hab.     N.  America,  in  the  Schuylkill  River.     (Cabinet  Prime.) 

This  species,  which  is  very  rare,  the  only  specimens  known  to  me  being 
those  in  my  collection,  is  not  very  liable  to  be  confounded  with  others.  Com- 
pared to  the  Sph.  o  c  c  i  d  e  n  t  a  1  e,  it  is  less  full,  the  beaks  are  more  prominent 
and  are  calyculate. 

32.  Sph.  sphaericum,  Anthony. 

Cyclas  sphcerica,  Anthony,  Bost.  Proc.  iv.  275,  1852. 

Animal  not  observed.  Shell  globose,  subequi- 
lateral,  transversely  oval ;  anterior  side  narrow, 
distended,  rounded  ;  inferior  margin  rounded ;  pos- 
terior margin  subabrupt ;  beaks  inclined  towards 
the  anterior,  large,  prominent,  calyculate  ;  valves 
slight,  very  convex,  interior  blue ;  strise  fine  and 
regular ;  epidermis  greenish  ;  hinge  margin  much 
curved  ;  cardinal  teeth  strong,  united  at  base  and 
disposed  in  the  shape  of  the  letter  V  reversed ; 
lateral  teeth  prominent,  very  distinct,  rather  short. 
Long.  5-16  ;  lat.  9-32 ;  diam.  3-16  inches. 

Hab.  N.  America,  in  the  Black  River,  Ohio.  (Cabinets  Anthony  and 
Prime.) 

Very  rare ;  I  have  never  seen  any  specimens  of  this  species  but  those  in 
Mr.  Anthony's  collection  and  in  mine.  Compared  to  the  Sph.  rosaceum. 
it  is  less  equilateral,  more  inflated  and  the  margins  are  less  rounded.

"      pellucida,  Prime,  Boston  Proc.,  iv.  277,  1852. 

Animal  not  observed.  Shell  rhombic-orbicular,  lenticular,  thin,  pellucid, 
very  slightly  inflated,  subequilateral :  anterior  side  narrower  ;  anterior  mar- 
gin rounded  ;  posterior  margin  nearly  a  straight  line  ;  basal  somewhat  curved  ; 
beaks  central,  calyculate,  approximate  at  apex  ;  strise  very  delicate  ;  epider- 
mis glossy,  light  greenish  horn  color ;  valves  slight,  very  little  convex  ;  inte- 
rior light  blue  ;  hinge  margin  very  nearly  straight ;  very  narrow  ;  cardinal 
teeth  diminutive,  united  at  base ;  lateral  teeth  slight,  narrow,  not  much 
elongated.

Long.  6-16;  lat.  5-16;  diam.  5-32  inches. 

Hab.  N.  America,  in  the  States  of  Maine,  Vermont,  Massachusetts,  Con- 
necticut, New  York  and  Ohio.  (Cabinets  Linsley,  Gould  and  Prime.) 

The  specimens  from  which  this  description  was  prepared,  the  same  ones 
from  which  Dr.  Gould  described  the  original  Cyclas  t  r  u  n  c  a  t  a,  are  pre- 
cisely similar  to  those  the  late  Prof.  Adams  sent  to  me  labelled  Cyclas  c  a  1  y- 
c  ulat  a,  from  Vermont,  and  which  I  described,  in  1852,  under  the  name  of 
Cyclas  pellucid  a.  This  specicies  is  undoubtedly  very  closely  allied  to 
the  Sph.  lacustre,  Ferussac  (Cyclas  calyculataof  authors)  of  Europe, 
but  still  the  differences  are  patent  enough  to  authorize  its  being  retained  as 
distinct.  Compared  to  the  Sph.  p  a  r  t  u  m  i  u  m,  the  Sph.  truncatum  is 
less  inflated,  transversely  less  broad,  the  posterior  margin  is  more  abrupt  and 
the  hinge  slighter.  The  young,  more  tumid  than  the  adult,  is  of  a  lemon 
yellow.  Found  not  uncommonly. 

34.  Sph.  lenticula,  Gould. 

Lucina  lenticula,  Gould,  Bost.  Proc.,  iii.  256,  1850. 

Cyclas  lenticula,  Gould,  Atlas  Explor.  Exped.,  pi.  36,  f.  528. 

Animal  not  observed.  Shell  rhombic-orbicular,  lenticular,  thin,  pellucid, 
very  slightly  inflated,  nearly  equilateral ;  anterior  side  narrower ;  anterior 
margin  curved ;  posterior  margin  abrupt,  inferior  rounded ;  beaks  central, 
calyculate,  approximate  at  apex;  strise  hardly  visible;  epidermis  glossy, 
light  greenish  horn  color ;  valves  delicate,  a  little  convex  towards  the  region 
of  the  umbones  ;  interior  light  blue  ;  hinge  margin  nearly  straight,  narrow  ; 
cardinal  teeth  hardly  visible,  united  at  base  ;  lateral  teeth  slight,  narrow,  not 
much  elongated. 

Long.  7-16  ;  lat.  6-16  ;  diam.  3-16  inches. 

(Cabinets  Gould,  Anthony  and  Prime.) 

Hab.     N.  America,  in  Carson  River,  California. 

This  species,  of  which  I  obtained  specimens  from  Dr.  Gould,  is  so  similar 
in  nearly  every  respect  to  the  Sph.  truncatum,  that  it  is  very  difficult  to  tell 
them  apart.  The  valves  of  the  Sph.  lenticula  are  perhaps  a  little  more 
convex  as  they  approach  the  region  of  the  beaks,  and  the  binge  margin  a 
little  more  curved  and  less  narrow.  The  young  shell  is  of  the  same  color  as 
tthe  adult,  whereas,  with  Sph.  truncatum,  the  young  is  of  a  lighter  color.

terior extremity  obliquely  subtruncate  above  and  rather  narrowly  rounded 
below  ;  cardinal  margin  long  and  straight ;  beaks  very  small,  compressed  and 
projecting  but  slightly  above  the  hinge,  located  nearly  half  way  between  the 
middle  and  the  anterior  end ;  surface  marked  by  moderately  distinct,  irregular 
lines  of  growth.

buccal  end  rounded ;  anal  extremity  obliquely  truncate  ;  basal  margin  semi- 
elliptical  or  broadly  rounded ;  beaks  obtuse,  tumid,  rising  somewhat  above

Cyclas  subelliptica,  M.  &  H.,  Ac.  N.  S.  Phil.  Proc.,  115,  1856. 

Shell  small,  elliptical-ovate,  somewhat  ventricose,  thin  and  fragile  ;  pos- 
terior end  narrower  than  the  anterior,  both  narrowly  rounded ;  base  semi- 
elliptical  or  semiovate  ;  cardinal  border  apparently  rounding  gradually  to 
both  extremities ;  beaks  not  much  elevated,  pointed,  incurved,  not  oblique, 
located  near  the  middle  ;  surface  indistinctly  marked  with  lines  of  growth. 

Long.  -24 ;  lat.  -14  inch. 

Hab.  Three  miles  above  Fort  Union,  Nebraska,  U.  S.  of  America.  Ter-

' '  The  beaks  are  so  near  the  middle,  and  curved  so  nearly  at  right  angles  to 
the  longitudinal  diameter  of  the  shell,  that  it  is  not  easy  to  determine,  espe- 
cially from  the  examination  of  mutilated  specimens,  which  is  the  posterior  or 
which  the  anterior  end.  As  we  have  only  seen  imperfect  specimens,  we  are 
not  sure  the  surface  markings  are  indistinct  on  unworn  shells." — M.  &  H. 

The  following  shells,  known  under  the  name  of  Cyclas,  must  be  excluded 
from  the  list  of  American  species  of  Sphaerium,  in  some  cases  because  they 
have  been  improperly  placed  in  this  genus,  and  in  others,  because  no  descrip-

Remarks.  This  interesting  species  is  very  unlike  any 
other  hitherto  found  in  Jamaica.  It  has  the  hirsute  char- 
acter of  Alcadia  hirsuta  C.  B.  Adams,  of  that  island,  and  in 
that  respect,  as  well  as  in  general  form  has,  to  a  remarkable 
degree,  the  aspect  of  a  Schasicheila,  without,  however,  the 
incised  peristome. 

I  am  indebted  for  this,  as  well  as  many  other  species,  to 
my  valued  correspondent  Mr.  C.  P.  Grloyne,  R.  E.,  who 
refers  to  it,  the  specific  name  having  been  communicated  by 
me,  in  his  Notes  on  the  Land  Shells  of  Jamaica,  Jour,  de 
Conchyliologie  XII,  p.  44.  January,  1872.

XIII.—  -Notes  on  specimens  of  Corbiculadce  in  the  Cabinet 

of  the  Jardin   des   Plantes   at   Paris,  and   on   the 

authorship  of  the  Encyclopedia  MetJiodique. 

BY    TEMPLE    PRIME. 
Bead  May  6th,  1872. 

I  had  tlie  opportunity,  in  1871,  of  making  notes  on  some 
of  the  Corbiculadce  in  the  Jardin  des  Plantes,  which  I  am 
induced  to  publish  in  the  hope  that  their  perusal  may  lead  to 
the  correction  of  some  errors  prevalent  in  regard  to  the 
species  of  this  family. 

Cyrena    orient  alls,  LAMARCK. 

This  species,  described  in  1818*,  is  represented  by  a 
single  valve,  which  I  found  to  agree 
with  the  shell  which  I  publishedf 
under  the  name  of  Corbicula 
Japonica.  —  Lamarck's  species  is 
represented  as  coming  from  China, 
mine  is  a  native  of  Japan. 

Corbicula  Japonica.  T_r  .  ..      .  1 

We  cannot,  however,  decide  as 

yet  positively  that  the  orientalis  and  the  Japonica  are  identi- 
cal, for  the  reason  that  Lamarck  refers  to  his  type  as  being 
in  his  own  Cabinet,  which  is  at  present  at  Geneva. 

Cyrena  truncata,  LAMARCK. 

Lamarck  in  his  description^  of  this  fossil  species  stated 
that  it  came  from  the  State  of  New  York.  There  is  one 
valve  of  the  truncata  which  evidently  belongs  to  the  Tertiary  ; 
it  is  intermediate  between  antiqua  and  cuneiformis  of  Eu- 
rope. 

As  already  stated  on  a  previous  occasion  §  I  doubt  the 
fact  of  this  species  having  been  found  in  N.  Y.,  but  think

that,  if  it  came  from  America  at  all,  which  I  hardly  believe, 
as  it  is  so  unlike  any  of  our  known  fossil  Cyrenm  or  rather 
Corbiculce,  it  is  a  native  of  one  of  our  Southern  States. 

The  truncata  is  labelled  as  having  been  purchased  from 
the  collection  of  Valenciennes  (the  father  of  the  late  Prof. 
Valenciennes). 

Cyrena    oblongra,    QUOY. 

M.  Deshayes  has  stated*  that  this  species,  a  native  of 
Vanikoro,  has  a  sinus.  I  called  attention  |  to  this  fact, 
remarking  that  it  was  the  only  instance  on  record  of  a  non- 
American  Cyrena  possessing  a  sinus,  qualifying  my  state- 
ment, however,  with  the  reservation,  that  I  had  never  seen 
any  specimen  of  oblonga. 

On  an  inspection  of  the  specimen  of  the  oblonga  at  the 
Jardin  des  Plantes,  I  detected  at  once  that  the  so-called 
Cyrena  was  nothing  more  or  less  than  a  Glauconome. 

I  am  enabled  consequently  to  uphold  the  proposition,  that 
none  of  the  lion-American  Cyrenaz  have  an  unbroken  pallial 
impression. 

Cyrena   placeiis,  HANLEY. 

Elsewhere  J  I  have  quoted  Mr.  Hanley  to  the  effect  that 
there  was  a  specimen  of  this  species  at  the  Jardin  des 
Plautes.  As  the  placens  is  not  personally  known  to  me,  I 
sought  for  the  specimen  in  question  with  some  eagerness ; 
unfortunately,  it  was  not  to  be  found. 

Note  on  the  "Encyclopedie  Methodique. " 

Being  frequently  obliged  to  consult  this  work,  I  was  much 
puzzled  to  know  whether  the  name  of  the  genus,  in  many 
cases  a  new  one,  at  the  top  of  the  plate,  was  the  only  evi- 
dence of  the  publication  of  the  genus,  or  whether  there

existed  some  published  record  of  the  same  not  so  widely 
distributed  as  the  plates  of  the  Encyclopedic,  and  to  clear 
up  my  uncertainty  I  entered  into  correspondence  with  M. 
Crosse  the  manager  of  the  Journal  de  Conchy liologie. 

M.  Crosse  wrote  me  that  to  make  the  information  the 
more  authentic  he  had  consulted  M.  Deshayes,  who  had  been 
one  of  the  contributors  to  the  Encyclopedic  Methodique. 
M.  Deshayes  sent  him  the  following,  which  I  have  trans- 
lated. 

"We  owe  to  Bruguiere  all  the  plates  of  Natural  History 
"of  the  Encyclopedic  Methodique  relating  to  the  Fers, 
"except  the  last  hundred  for  which  we  are  indebted  to  Lam- 
"arck.  The  names  of  the -genera  printed  at  the  top  of  the 
"plates  are  the  only  indications  which  exist  relating  to  these 
"useful  creations,  which  the  author  would  have  placed  on 
"record  in  text,  had  not  a  premature  death  prevented  him 
"from  so  doing.  With  reference  to  the  existing  text,  Bru- 
"guiere  published  one  .volume,  which  ends  with  the  genus 
"Conus.  It  was  in  1828  that  I  was  entrusted  with  the  fin- 
ishing of  this  text;  my  first  volume  commences  with  a  sup- 
plement to  the  letters  a,  b,  c ;  it  was  published  in  1830; 
"my  second  volume  is  of  183-2;  so  that  the  text  of  the 
"Encyclopedic  Methodique"  concerning  Mollusca  is  com- 
" posed  of  three  volumes,  one  by  Bruguiere  and  two  by  me."

Deshayes,  Nov.  24th,  1869.)
